Abstract
FLEXIBLE CABLE ASSEMBLY
ABSTRACT
A flexible cable assembly for rotary actuation as in automobile speedometer or tachometer cable, or for linear actuation, for example in a push-pull remote control cable and to a method of manufacturing a plastic liner of the cable assembly, comprising a power transmitting core member and a tubular casing that includes an outer housing and a spiral cut tubular liner 10 with internal ribs 14.
The liner 10 is constructed by extruding a cylindrical tube with at least one internal longitudinally extending rib 14. The tube is then cut helically so as to offset circumferentially the rib segments 14 on adjacent turns of the strip 11, thereby providing internal support for the core member.

FLEXIBLE CABLE ASSEMBLY
DESCRIPTION
The present invention relates to a fle~ible cable assembly for rotary actuation, as ln an automobile speedometer or tachometer cable, or for linear actuation, for e~ample in a push-pull remote control 5. cable, and to a method of manufacturing a plastic liner of the cable assembly.
According to the invention there is provided a fle~ible cable assembly comprising a motion-transmitting core member, and a tubular casing 10. supporting the core member for movement therein the casing including an outer housing and an inner plastic tubular shaped liner formed by a helical strip and having radially inwardly extending ribs along an inner surface thereof for supporting the core member, the 15. ribs e~tending substantially longditudinally with respect to the liner with a segment of each respective rib on one side edge of the helical strip being offset circumferentially with respect to the corresponding immediately longitudinally adjacent segment of the rib 20. on the adjacent side edge of the helical strip.
According to the invention there is also provided a method of forming a liner for a fle~ible cable assembly the method including forming a flexible generally cylindrical tube with at least one generally 25. longitudinally e~tending rib on an interior surface of ~4691~;~
the tube, cutting the tube to form a helical tubular strip ~ith at least one segment of the rib on each turn thereof, and circumferentially offsetting the segments of the rib on adjacent turDs of the strip.
5. Embodiments of the invention will now be described by way of example and with reference to the accompanying drawings in which:-Figure 1 is a p~rspective view of a liner forming part of the flexible cable assembly, 10. Figure 2 is a cross-sectional view taken along the line II - II of Figure 1, Figure 3 illustrates the flexible cable assembly including the part shown in Figure 1;
Figure 4 is a side elevation of an apparatus for 15. performing part of the method of manufacturing the liner of Figure 1;
Figure 5 is an end elevation of the apparatus of Figure 4 taken along line V-V of Figure 4; and Figure 6 shows a cutting blade for use in the 20. apparatus of Figures 4 and 5.
~Z~69~
With reference to Figures 1 and 2 a conduit liner 10 for use in a cable assembly is shown. The liner 10 is formed of an e~truded plastic tube of polypropylene, a polyamide material such as is 5. available under the trademark Nylon, or other similar material. The tube has a plurality of molded internal ribs 14, shown here as six in number and equally spaced. A continuous and regular spiral cut 12 is made along the entire length of the tube, forming a helical 10. strip 11. In Figure 1 one of the ribs 14 is shown in phantom outline, and is seen to have been broken by the cut 12 into a plurality of discontinuous ribs denoted by 14a, 14b, etc.
When the spiral cut is made in ~he tube, the tube 15. tightens or winds up slightly. The tightening is caused by several factors such as: closing the gap formed by the cut and thereby reducing the tube radius;
mechanical stress e~erted by the cutting blade on the tube during the cutting operation; or reliei of 20. torsional pre-stresses in the tube that are created in the extrusion operation. Generally, an e~truded tube has a torsional stress throughout its length, and releasing ~his stress by making a helical cut causes the adjacent turns of the helical strip to shift cir-25. cumferentially with respect to each other.
The tightening of the cut tube causes the segmentsof the ribs 14 on adjacent turns of strip 11 to become ~246~
offset or misaligned. Preferably, they are circum-ferentially offset from each other, on any given turn, by about half the distance between the ribs 140 The misaligned ribs, being circumferentially spaced, 5. provide support throughout a ~ull 360 range, resul~ting in smooth motion of a central core member.
In Figures 2 and 3 a central aperture 16 is defined by the strip 11 and the ribs 14 for accommodating and supporting an inner centre core 10. member 22 in contact with the ribs 14. The lay of the wrapped wires on the outer surface of the core member 22 and spiral cut 12 are shown in Figure 3 to have a left-hand lay. Such a lay relationship is particularly useful for counterclockwise rotation of 15. the core member 22, that is, in the direction of arrow A as seen in Figure 3. When the lay of the spiral-cut helical strip 11 corresponds in this way to the lay and the direction of rotation of the rotating core member 22, the lubricant is essentially suspended 20. within the liner 10, and upward pumping of the lubricant is thereby prevented. The rotation of the core member 22 in the direction of the lay of the helical strip 11 also opens up the turns of the strip 11 and works the lubrican-t into the gaps between 25. the turns, where the lubricant then remainsO Thus the arrangement provides improved lubricating capacity and retention.
~2469G4 In Figure 3 the cable assembly is shown in which the conduit liner 10 is surrounded by an internal strenghtening layer 18, which in turn is covered by a soft plastic tubular e~trusion cover 20 to provide both 5. strength and watsr-tight integrity. The e~truded plastic cover 20 further improves on the reduction of noise obtained by the combina+ion of offset ribs 14 and the spiral cut 12. The internal strengthening layer 18 may be ~ade of wire or other materials, including 10. spaced wound flat wire, full complement stranded round wire, or spaced stranded round wire. In some instances when, for example tensile and compressive strength are not a major requirement, the extrusion cover 20 may be applied directly over the helical strip 11.
15. Figures 4 to 6 show apparatus for performing part of the method of manufacturing the liner 10. A
cylindrical rotating cutting head 30 has an open cylindrical central aperture 32 into which the ribbed plastic tube to be spirally cut is fed. The inside 20. diameter of the aperture 32 is approximately the same as the outside diameter of the tube. A rotating coa~ial shaft 44 is attached to the head 30 for receiving a driving force from a power source (not shown) to rotate the head 30. A diagonal slot 34 in 25. one side of the head 30 communicates with the exterior of the head 30 and with the central aperture 32. A
slot 34 forms a selected angle, designated as ~ in Figure 4, with the longitudinal axis of the aperture 32.
6~
A cutting blade 36 having a cutting edge 38 is inserted into the slot 34 from the exterior of the head 30, and is secured by se~-screws (not shown) in threaded holes 40 and 42 in the head 30. The blade 36 5. is inserted far enough into the aperture 32 for the cutting edge 38 to engage and cut the adjoining portion of the tube wall and ribs. As shown, the length of the cutting edge 38 is slightly less than the diameter of a cross-section of the head 30.
10. It will be appreciated that the angle of the blade 36, the rotational speed of the head 30 and the feed of the tube through the head 30 are directly interdependent to produce the requisite cut, the material deforming slightly during the cutting 15. operation to accommodate the planar blade.
The angle x is selected according to several considerations. If the angle is large, the pitch of the spiral cut 12, that is, the spacing between turns, will bP small aDd the conduit liner lO will be more 20. fle~ible and better able to maintain its round shape at a bend. On the other hand, cutting into a smaller pitch is slower and thus less economical. Also, a substantial loss of support takes place if the pitch is very small~ A desirable pitch range has been found to 25. e~tend from about 3.18mm up to a maximum of 9.52mm with a preferred pitch of 6.35mm.
